What is the primary purpose of building garden walls?

The primary purpose of building garden walls is to enhance the aesthetics and elegance of outdoor living spaces. Garden walls can create visual interest, define areas within a yard, and serve as a decorative element that complements landscaping. They often help to frame gardens, provide a backdrop for plants, or create a sense of enclosure, making outdoor areas more inviting and organized.

While there are other functions that garden walls can serve, such as providing security or acting as a sound barrier, these are not their main purpose. The charm and beauty they add to gardens and outdoor settings is what primarily drives the decision to construct them.
